Title text:
Unstoppable force-carrying particles can’t interact with immovable matter by definition.
Transcript:
[An arrow pointing to the right and a trapezoid are labeled as ‘Unstoppable Force’ and ‘Immovable Object’ respectively.]
[The arrow is shown as entering the trapezoid from the left and the part of it in said trapezoid is coloured gray.]
[The arrow is shown as leaving the trapezoid to the right and is coloured black.]
[Caption below the panel:] I don’t see why people find this scenario to be tricky.

They met, they just didn’t interact. Kinda like me at a work party.
There is no force without interaction, just linear momentum.
“where’s the food and booze?”
That just moves the problem, what happens if I put a piece of paper between them? Unless they don’t interact with anything they still face the same problem.
I mean we have these in the universe, one example of an unstoppable force is neutrinos. These tiny particles certainly seem to contain a whole lot of energy, moving close to the speed of light. But just try to stop one.
